Our review, for instance, finds that the embodied energy rebound for most cost - effective efficiency improvements is likely to be less than 15 percent but more significant for efficiency improvements with long payback periods, including some building efficiency measures.

R - House presents an affordable, innovative paradigm for minimal to net - zero energy consumption embodied in architecture that is meant to nurture the spirit and engage the community as much as it is meant to perform in terms of cost and sustainability.

Clearly, given all of those costs, it's obvious that the embodied energy is not going to be that significant.

So from back - up and embodied energy considerations alone it seems that the report's conclusions about the amount of excess capacity, and that total system capital cost, might be less than half the actual figures.
